Well I parked my 97 obs in June and just got it running yesterday. I took my F350 sc/lb and put a cc/ex. short box on it with a 3" body lift to get the cc to clear the frame hump.
It was mainly a body change job, the only mechanical changes I did were an ebpv delete, added beans brass o-ring gaskets in the up-pipes, put in an electric fan, resealed the oil pan with the grey ford cement(easier with the cab off!!).
Now I got a bad oil leak, seroiusly like 3 liters per 50kms. (Sorry I'm canadian; 3.78 liters is 1 gallon and 30 miles is around 50kms) When the truck is running in idle it is a stream and it is leaking out the transmission inspection plate only when running and appears to be coming from the passenger side. I removed the plate and see a drip coming off the area above the oilpan in the rear main seal area.
So I go to fill up some oil in the oil fill cap and all of a sudden I got fresh new oil dripping out the back in the same area above the oilpan out the rear main seal area without it running.
Now I also noticed oil is also blowing out the oil fill cap when driving. I did a ccv mod years ago and checked the hose for plugs and it is clear (just thinkin I was pressurizing the crank case). And the oil valley and turbo pedistal is dry, the oil pan has no drips down it, and the valve covers are torqued tight. I can't see oil above the transmission it all seems dry( I have more room to see with the 3" body lift to look).
Now with the fresh oil leaking when I fill it I think Valve cover gaskets, but I realize there is a rear engine cover on my motor that appears to be behind the tansmission could this cause fresh oil to leakout somewhere? I cant see any oil in the inspection hole, only oil dripping of the rear main seal area.Is there an area hidding behind the transmission that could need a new seal or o-ring?
I know this was a big read, but I like to be thorough and give as many details as possible. Thanx for reading this and any input you could give me.

 

Well after playing for a couple hours i think I need to reseal the oil pan ; it seams to leak right below the rear main seal as i put a rag above the pan joint and oil dripped below it. I think the oil fills through the passenger head and drains to the back of the motor down the back of the block and catches the pan lip and thens leaks out right there. Its gonna be a fun one now as I need to pull da flippin motor and have a real fight I'll try to lift it as high as i can and maybe cheat it but then i gotta remove the pick up tube aaargh. Well here it goes.

 

good luck man. i need to pull my turbo off, i hear that can be a pain in butt , but im sure that would be easyire with the cab off also.

 

Thanks bud. It was easier with the cab off but now its all back together so its gonna be hard. We'll get it. Their only nuts and bolts, lol, just wish I could have done it right the first time

The turbo is ok to pull just the back bolts are a bitch, I'm on my third stock turbo so I got it down pat on swappin them out.
